This HTS code, 9902.04.73, pertains to a specific synthetic insecticide, Cypermethrin. While its primary chemical description and CAS number are provided for precise identification, its classification within Chapter 99 signifies its treatment under temporary legislation or special import provisions. The notation "(provided for in subheading 2926.90.30)" indicates that, absent these special provisions, Cypermethrin would typically be classified under heading 2926, which covers nitriles and their derivatives. Therefore, this entry signifies a temporary modification or restriction related to the importation of this particular chemical compound, distinct from its standard chemical classification.

As a leaf node, this category does not have further subdivisions. Its existence within Chapter 99 is crucial for importers and customs brokers to understand that the standard classification rules might be superseded by specific, temporary import requirements or duty rates associated with this product. It highlights the dynamic nature of HTS classifications, where international agreements, domestic legislation, or agricultural protection measures can lead to specific entries under the temporary legislation chapter.
